DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures the reference numeral indicates generally a load handling system constructed in accordance with the invention.

The load handling system 20 includes a helium filled balloon 21 in the shape of ring having a guide fin 22 mounted thereon to stabilize the balloon in the transient air currents. A flexible electric line 23 extends from the balloon 21 to a house or building 24 where it is connected to the conventional electric circuits. An electric wire 25 depends from the balloon 21 and is a continuation of the electric wire 23. The electric wire 25 is secured to a load carrying device generally indicated at 26 and described in detail below. A grocery store is generally indicated at 27 in FIG. 1 to illustrate the usefulness of the device in transporting groceries from the grocery store 27 to the building 24.

The load transporting device 26 includes a fan wheel housing 28 of generally cylindrical form and having perforations 29 formed in its outer periphery. The fan wheel housing is formed of plastic or aluminum and has a pair of funnel members 30, 31 secured respectively to the upper and lower faces of the fan wheel housing 28. Perforations 32 are formed in the upper and lower faces of the fan wheel housing 28 and communicate the interior of the fan wheel housing 28 with the interior of the funnels 30, 31. A four-bladed helium filled rotor 33 is mounted centrally of the fan wheel housin 28 on a shaft 34 which extends to an electronic motor 35 w ich is adapted to rotate the rotor 33. The rotor 33 is provided with valves 36 at the end of each blade through which helium is released at a predetermined R.P.M. of the blade.

An inflatable air tube 37 is secured to the funnel 30 in encompassing relation thereto and in contact with the fan wheel housing 28. A second air tube 38 identical to the balloon ring 37 is secured to the funnel 31 in encompassing relation thereto and in contact with the fan housing 28. The air tubes 37, 38 are formed of flexible gas retaining material and are adapted to contain air or helium as desired. Tubes 39 extend from a manifold 40 to the balloon rings 37, 38 and provide means for filling the air tubes 37, 38 with air or helium.

A control handle 41 is pivotally secured at 42 to a frame member 43 depending from the fan wheel housing 28 in axial alignment therewith and the control handle 41 contains a plurality of control switches (not shown) for controlling the operation of the system by hand. A balloon chute 44 completely encompasses the load handling device 26 and is open centrally of the bottom thereof at 45. The chute 44 is closed with a zipper 46 at the op thereof.

A plurality of air rings 47 are mounted in the funnel 30 and a second plurality of air rings 48 are mounted in the funnel 31. The air rings 47 assist in supporting the payload carried by the device 26 which can be inserted therein by opening the zipper 46. When it is desired to transport the device 26 from place to place it can be rolled on its circumference by using the handle 41 as can be seen in FIGS. 9, l0 and 11 and it can be rolled on wheels 49 mounted on the funnel 31 if it is desired to maintain the device 26 in an upright position.

Air is drawn down through the funnel 30 by the rotor 33 and some of the air is expelled through the funnel 31, as shown by the arrows in FIG. 3.

In the use and operation of the invention the fan wheel housing 28 delivers air from its outer rim and also delivers air from the center up or down and can deliver helium from the outer rirn. The balloon chute 44 is inflated with air and when helium is delivered by the outer rim of the fan wheel housing 28 the air forces the helium to the top of the chute 44 and the air then passes by the air tube 38 and out the bottom opening 45 of the chute 44. Rotation of the rotors 33 creates the air flow necessary to float the device 26 and carry the required payload. In the event that a source of electricity is unavailable the motor 35 can be operated with batteries independently of the cable 25.

Having thus described the preferred embodiment of the invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.
